They are ideal for preserving comic book collections stored in short boxes, long boxes, storage cabinets, safes, and other enclosed environments. These humidity-control beads use a moisture-sensitive 2-way system that both absorbs excess humidity and releases moisture as needed to help maintain a stable storage environment for comic books and other paper-based collectibles.\u003c\/p\u003e\n\u003cp\u003eCollectors and preservation professionals often target humidity levels around 50% RH for paper-based collections, making environmental consistency an important part of long-term comic book storage. RH Shield™ 50% RH humidity-control products help reduce humidity fluctuations inside enclosed storage environments, supporting more stable conditions for raw comics, key issues, professionally graded comics, and entire comic book collections.\u003c\/p\u003e\n\u003cp\u003eOur silica beads are the same type of material used to help protect valuable collections housed by museums, archives, libraries, and private collectors. If you have invested time and money building a comic collection, proper storage conditions should be part of that investment.\u003c\/p\u003e\n\u003cp\u003eUnlike standard silica gel products that are designed only to absorb moisture, RH Shield™ is engineered to both absorb and release moisture to help maintain a stable relative humidity. RH Shield™ will never wear out as long as it is properly maintained and can be refreshed as needed with distilled water.\u003c\/p\u003e","brand":"RH Shield","offers":[{"title":"50%","offer_id":68325581291631,"sku":"RHS900T4R50","price":16.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2018\/2073\/files\/900T4R50_stock.jpg?v=1791237637","url":"https:\/\/rhshield.com\/products\/small-comic-books-humidity-beads-humidifier-tube-for-300-cu-in","provider":"RH Shield","version":"1.0","type":"link"}
